<p>在使用vue-router时，我们需要做的就是把路由映射到各个组件，vue-router会把各个组件渲染到正确的地方。</p>

<p>至此，我们初步创建了一个带路由的登录页面组件。</p>

<p>Vue中使用路由也折腾了一小会，不过vue的debug信息写得很详细哦，对哪里出问题了有个比较清晰的了解呢。<br><a href="https://github.com/godbasin/godbasin.github.io/tree/blog-codes/vue-notes/2-create-login" target="_blank" rel="external">此处查看项目代码</a><br><a href="http://vue-notes.godbasin.com/2-create-login/index.html" target="_blank" rel="external">此处查看页面效果</a></p>
